Swedish private equity firm EQT is seeking to sell medical-device company Atos Medical for about €1 billion ($1.1 billion), according to people familiar with the situation on March 1.

Atos Medical is based in Malmö, Sweden, and makes products used in the treatment of ear, nose and throat conditions. The company specialises in products for patients who have had a total laryngectomy-where their voice boxes are surgically removed. Its Provox voice prosthesis helps patients to speak again.
